Answer:
Step-by-step explanation:
It is a rectangle, so both sides are equal. Thus 2x+6=5x-9
SOLVE, SUBTRACT 2x
6=3x-9 THEN ADD 9
15=3x THEN divide by 3
5=x
Plug in x to either side 2(5)+6, to get side length of 16
Then area of a rectangle is lengthxwidth=AREA
substitute what you know 16(y)=48
Divide by 16, thus y=3
Answer:
Yes
Step-by-step explanation:
5/4 = 1 1/4 or 1.25 and that I'd greater than 1
Linear functions parabola mostly things in algebra
If f(x)=2x-1 just plug in the 3 where x is. So it would be 2(3)-1=5
